Astro Academy: Principia - circular motion

This collection of videos show ESA Astronaut, Tim Peake, on the International Space Station, demonstrating circular motion.  In this free-fall environment, Tim can demonstrate how objects move in a circular path without the observed effects of gravitational acceleration with similar experiments performed in the classroom.  The resources also contain videos where the motion has been tracked using free online software, called Tracker.  The Tracker files are also provided as part of the resources.
